Filed: 1951-12-19
Abstract: 714,091. Purifying asphalt by wet separation. BARBER OIL CORPORATION. Dec. 19, 1951, No. 29761/51. Class 82 (2)  Silica particles exceeding 20 microns in diameter, and vegetable matter are removed from crude Trinidad Lake asphalt by a process involving classification in water. In the embodiment shown, asphalt is broken and then ground in a rod-mill 6 and the vegetable matter strained out. The ground asphalt is then jigged at 8, or treated on a classifying table, to remove quartz over 50 mesh and the product is classified, e.g. in a rake classifier 9 to return material over 50 mesh to the rod-mill. The product then passes through two classifiers 10, 12, in series, each removing material of less than 20 microns which is received by a thickener 11. The underflow of the second classifier is treated by froth flotation to obtain the asphalt content which is aga:n classified to remove particles of less than 20 microns and to return them to the thickener. The underflow is treated in a ball-mill 16 before being classified 17, to remove the small particles as before. The underflow of this last classifier 17 is returned to the inlet of the second classifier 12 of the series pair. The sludge from the thickener 11 is filtered, treated, with a flux in a heated mixer, and finally dried and ground in a dispersing mill. The flotation reagents used to float the asphalt comprise xylol, kerosine 0.1, pine oil, cresylic acid, tetra-sodium pyrophosphate, and glassy sodium phosphates.
